Out of curiosity, if I were to buy a domain with a name relevent to the keywords within a given specific Adgroup and then forward and mask it to the actual landing page from my main domain/hosting account. Is that: A.) Compliant with Google? B.) Will my specific landing page of the actual domain still be optimized for relevency as I will have the landing page be relevent to the adgroup's keywords? Any other thoughts, suggestions? Thank you!
